Winter pregnancy sow feeding management technology

In winter, the cold weather and short illumination time have adversely affected the normal growth and development of pregnant sows, and attention should be paid to strengthening feeding and management.

First, reduce the number of embryos died

After the sow is pregnant, the zygote is susceptible to various factors and die in the initial period of the 9th to 13th day of the value of the sow.

The second death peak occurred on the third day after pregnancy and the two deaths accounted for 30% to 40% of the total number of zygote;

The third peak of death occurred 60 to 70 days after mating.

Production can be improved by feeding and management to improve the environment of the pig house and minimize the loss of embryos. The temperature of the pig house is maintained at 16-22°C, and the relative humidity is maintained at 70%-80%; the feed quantity after mating should be reduced to the original lower level, but the quality full price should be guaranteed; keep the house clean and hygienic so as to reduce The chance of infection.

Second, choose the appropriate feeding method

Generally can use the following three ways:

One is to grasp the middle of the two: This method is suitable for the poor sows.

That is, after 20 days before mating and 10 days after mating, the concentrate is fed. When the body condition is restored, the green feed is mainly adopted. Feeding is carried out according to the feeding standard until 80 days after pregnancy, then the concentrate is fed, but the nutritional level in the later period should be higher than the previous period. .

The second is the pre-coarse after-finishing: This method is suitable for breeding sows with good pre-condition.

That is, in the pre-pregnancy period, more of the green roughage is fed and later the concentrate is fed.

The third step is to climb up step by step: This method is suitable for the sows that are born and the sows that are bred during lactation.

That is to say, in the early stages of pregnancy, mainly the roughage, gradually increase the proportion of concentrate, and accordingly increase the protein and minerals in the feed. However, care should be taken to reduce the diet by 10 to 20% during the week before the sow is born.

Third, supply the mother sufficient nutrition

The nutrients that pregnant sows obtain from the diet first satisfy the growth and development of the fetus, then supply their own needs, and store some nutrients for breastfeeding. Therefore, satisfying the supply of nutrients is necessary to ensure normal growth and development of sows and fetuses. Therefore, in addition to supplying enough energy and protein feed for sows, it should also ensure that vitamins and minerals are met.

Fourth, the use of reasonable feeding technology

The diet fed to pregnant sows must have a certain amount of green roughage in addition to hygiene and quality assurance, so that the sow will feel full after eating, and will not oppress the fetus.

Green roughage is rich in amino acids, vitamins and trace elements, which is conducive to the normal growth and development of the fetus, while providing adequate drinking water.

It is forbidden to feed mildewed, frozen, poisonous, and irritating feedstuffs, otherwise it is easy to cause miscarriage; at the same time, feedstuffs are not to be changed at will. Feeding green roughages should be fed less frequently and the sows should be allowed to drink clean water at any time.

V. Feeding during the pre- and post-pregnancy period: About 20 days after the sow is pregnant, the embryo is very susceptible to environmental conditions.

Special care should be given to husbandry and management, and high-quality full-priced feed should be given; In the last month of pregnancy,

On the one hand, the weight of the fetus increases dramatically and requires a lot of nutrients.

On the other hand, due to the increase in the size of the uterus, the digestive organs are squeezed, which can easily lead to insufficient feed intake for pigs.

Therefore, nutrient-rich diets, especially protein feeds, should be fed.

VI. Practically strengthen management

The focus of managing pregnant sows is to do a good job

In the daily management should pay attention to the following points:

(1) Pregnant sows are best kept on a single lap, the dough should be flat, dry and clean to keep it cool in winter and cool in summer. The compost pit should be shallow and the slope should not be too steep.

(2) Within the first month after the sow is pregnant, she should eat well, sleep well and exercise less in order to restore her physical strength and sensation. However, she should exercise more during the second trimester of pregnancy. In the later period, she should reduce the amount of exercise so that her sows can move freely. Activities should be stopped 1 week before childbirth.

(3) In the rain, snow or too cold weather, exercise should be stopped to prevent slipping or abortion due to severe contraction of the uterus caused by freezing.

(4) It is forbidden to whip, cross the ditch to cross the gate more slowly, prevent crowding and rapid eviction, sharp turn and so on. (5) Progesterone should be injected promptly if there are signs of abortion.

Seventh, do a good job of prenatal preparation

Cold in winter, need to do windproof warm work. It is advisable to set up a special delivery room for sows. The maternity room must be warm and dry. The humidity should be kept between 65 and 75%. It should be comfortable and quiet, with plenty of sunshine and fresh air. The temperature should be maintained at 22-23°C. For sows with good lyrical and well-developed breasts, 3-5 days before birth should be reduced, gradually reduced to 1/2 or 1/3 of the feeding level during pregnancy, and green and juicy feed should be stopped.

For those sows with poor body condition and poor breast development, not only do they not reduce the material before giving birth, they should also feed some feed rich in protein and vitamins.

The sow is rushed to the delivery room 3 to 5 days before delivery and is prepared for delivery and adequate litter.
